Determination of the Operating Frequency and Pipe Design of Inverter Air-conditioner considering Dynamic Characteristics of Inverter Rotary Compressor

진동 특성 파악을 통한 인버터 에어컨의 운전 주파수 및 파이프 형상 결정

The reduction of chopping noise generated from inverter compressor and the piping design reducing vibration are the most important items in the quality of air conditioner. The chopping noise is identified by the study of the relationship between carrier frequency and natural frequency of the compressor shell. The high carrier frequency is the key factor in reduction of carrier noise. To keep the natural frequencies of the system as far as away from the operating frequencies appears to be the most important factor in the design of piping system.
